Can chlamydia cause infertility? It is one of the most commonly asked questions in sexual health, and with good reason. Chlamydia is the most frequently reported bacterial sexually transmitted infection in the UK, yet it often produces no obvious symptoms at all. Left undetected, chlamydia infertility risks become significant — the infection can silently affect reproductive organs over months or even years. Understanding the long term risks of chlamydia is essential for anyone who is sexually active, particularly those planning for a family in the future. Early confidential STI testing in London remains one of the most effective steps you can take to protect your reproductive wellbeing.
Direct Answer: Yes, chlamydia can cause infertility if it remains untreated. The infection may spread to the reproductive organs, leading to scarring, inflammation, and damage to the fallopian tubes in women or the epididymis in men. Because chlamydia is often asymptomatic, many people carry the infection without realising, which increases the risk of long-term reproductive complications.
Is Chlamydia a Viral or Bacterial Disease?
A question that often arises is whether chlamydia is a viral or bacterial disease. Chlamydia is caused by the bacterium Chlamydia trachomatis, making it a bacterial infection rather than a viral one. This distinction is important because bacterial infections can generally be addressed through appropriate healthcare services, whereas viral infections often remain in the body indefinitely.
Understanding how chlamydia can be transmitted is equally important. The infection spreads primarily through unprotected vaginal, anal, or oral sexual contact. It can also be passed from mother to baby during childbirth. The likelihood of contracting chlamydia increases with the number of sexual partners and the absence of barrier protection. In the UK, chlamydia is particularly prevalent among those aged 15 to 24, though it can affect anyone who is sexually active regardless of age.
How Quickly Does Chlamydia Show Up?
One of the trickiest aspects of chlamydia is its silent nature. So, how quickly does chlamydia show up after exposure? Typically, if symptoms develop at all, they may appear within one to three weeks following contact. However, how long does it take for chlamydia to show varies considerably between individuals. Some people develop mild signs relatively quickly, while others notice nothing for months.
Perhaps more concerning is the question: can you have chlamydia for years and not know? The answer is yes. A significant proportion of those infected — estimated at around 50% of men and 70% of women — experience no symptoms whatsoever. This means you could carry the infection without any indication, and how long can you have chlamydia without knowing depends entirely on whether you undergo screening. Without testing, the infection can persist silently for an extended period, during which it may cause progressive internal damage.
Signs and Symptoms of Chlamydia
Although chlamydia is frequently asymptomatic, recognising the potential signs and symptoms of chlamydia can prompt earlier testing. When symptoms do occur, they tend to differ between men and women.
In women, signs may include:
- Unusual vaginal discharge
- Discomfort or a burning sensation during urination
- Pain in the lower abdomen
- Bleeding between periods or after sexual contact
In men, signs may include:
- White, cloudy, or watery discharge from the penis
- A burning or itching sensation at the tip of the urethra
- Discomfort during urination
- Testicular tenderness or swelling
It is also worth being aware of oral chlamydia, which can develop following unprotected oral sexual contact. Oral chlamydia may cause a sore throat, redness, or mild discomfort in the mouth or throat area, though it frequently goes unnoticed entirely. Knowing how to tell if you have chlamydia is not always straightforward, which is why regular screening is so valuable — particularly when symptoms alone are unreliable indicators.
Can Chlamydia Cause Infertility in Women?
The link between chlamydia and female infertility is well-documented in medical literature. When left untreated, the bacteria can ascend from the cervix into the upper reproductive tract, leading to pelvic inflammatory disease (PID). PID is an infection of the uterus, fallopian tubes, and surrounding structures, and it is one of the primary pathways through which chlamydia infertility occurs in women.
The inflammation caused by PID can result in scarring and adhesions within the fallopian tubes. This scarring may partially or completely block the tubes, preventing eggs from travelling to the uterus and making natural conception significantly more difficult. The chlamydia long term damage to the fallopian tubes is often irreversible, even after the underlying infection has been addressed.
What makes this particularly concerning is the silent progression of the disease. Many women who develop PID from chlamydia are completely unaware until they experience difficulty conceiving. By that stage, the internal damage may already be extensive. This underscores the importance of proactive screening — identifying the infection through testing, and then seeking medical advice, before it reaches the reproductive organs can substantially reduce the risk of fertility complications.
Can Chlamydia Affect Male Fertility?
While discussions about chlamydia and fertility often focus on women, the long term chlamydia effects on male reproductive health should not be overlooked. In men, untreated chlamydia can spread to the epididymis — the coiled tube at the back of the testicle that stores and carries sperm. This condition, known as epididymitis, causes inflammation, pain, and swelling.
If epididymitis recurs or becomes chronic, it may lead to scarring within the epididymis, which can obstruct the passage of sperm. This obstruction may reduce sperm count or impair sperm quality, both of which can affect fertility. The chlamydia long term consequences for men, though sometimes less discussed, are a genuine concern. Evidence also suggests that chlamydia may directly affect sperm DNA integrity, potentially influencing conception outcomes even when sperm counts appear normal. Awareness of these risks reinforces the value of routine screening for sexually active men.
Can Chlamydia Go Away On Its Own?
A commonly held misconception is that chlamydia might resolve without intervention. So, can chlamydia go away on its own? The straightforward answer is no. Without appropriate healthcare services, the infection will persist in the body and may continue to cause internal damage over time. There is no evidence to suggest that the immune system can reliably clear a chlamydia infection on its own.
On a more reassuring note, is chlamydia curable? Yes, chlamydia is widely regarded as a curable infection. Once identified through testing, you can seek medical advice to address the infection through appropriate healthcare services. The key point is that identification through testing must come first. If you are concerned about possible exposure, seeking chlamydia testing services is a sensible and straightforward step. Can chlamydia be cured once it has caused structural damage to the reproductive organs? Unfortunately, while the infection itself can be resolved through appropriate healthcare services, any scarring or damage that has already occurred may be permanent — making early detection critically important.
Transmission Risks & Protection
Understanding how chlamydia spreads is fundamental to reducing risk. A frequently asked question is whether you can contract chlamydia without having intercourse. The answer is yes — chlamydia can be transmitted through oral and anal sexual contact, as well as through sharing unwashed intimate items. It can also be passed through genital-to-genital contact without full penetration, which means that any form of intimate contact carries some degree of risk.
Another common query is whether you can get chlamydia using a condom. While condoms significantly reduce the likelihood of transmission, they do not eliminate the risk entirely. Incorrect use, slippage, or contact with areas not covered by the condom can still allow the bacteria to spread. Condoms remain one of the most effective forms of barrier protection available, but they work best as part of a broader approach to sexual health that includes regular screening.
Long Term Risks of Untreated Chlamydia
Beyond fertility, the long term risks of chlamydia extend to a range of other reproductive and general health complications. In women, untreated infection may increase the risk of ectopic pregnancy — a potentially serious condition where a fertilised egg implants outside the uterus, often within a damaged fallopian tube. Chronic pelvic pain is another documented consequence of the chlamydia long term damage caused by ongoing inflammation and scarring.
For men, persistent infection can lead to chronic prostatitis or ongoing discomfort in the pelvic region. In both sexes, untreated chlamydia may also increase susceptibility to other sexually transmitted infections.
The chlamydia long term consequences are best understood through a summary of affected areas:
| Area Affected | Potential Impact | Why Early Testing Matters |
|---|---|---|
| Fallopian Tubes | Scarring and blockage, reducing the chances of natural conception and increasing ectopic pregnancy risk | Early detection through testing allows you to seek medical advice before irreversible tubal damage occurs |
| Uterus | Inflammation (endometritis) that may affect implantation and contribute to chronic pelvic pain | Testing can detect infection before it ascends to the uterus, allowing you to seek medical advice promptly |
| Epididymis | Inflammation and potential scarring that may obstruct sperm passage and reduce fertility in men | Screening before symptoms develop enables you to seek medical advice and reduce the risk of long-term damage |
| Throat (Oral Chlamydia) | Sore throat, redness, and discomfort; may act as a reservoir for reinfection of genital sites | Awareness of oral transmission routes ensures comprehensive testing and reduces reinfection risk |
When Should You Consider Chlamydia Testing?
Deciding when to test is a personal choice, but there are several situations where screening is particularly worthwhile. You may wish to consider testing if:
- You have had a new sexual partner or multiple partners
- You have had unprotected sexual contact
- A current or previous partner has informed you of a positive result
- You are experiencing any of the symptoms described above, however mild
- You are planning to conceive and want to rule out underlying infections
- You simply want peace of mind about your sexual health status
Testing is a straightforward process, typically involving a urine sample or a swab. Results are usually available within a few days, giving you clear and actionable information about your health. If you are unsure whether testing is appropriate for your situation, seeking appropriate healthcare services for guidance is always a reasonable step.

Frequently Asked Questions
Can chlamydia cause infertility?
Yes, untreated chlamydia can cause infertility. The infection may spread to the reproductive organs, causing scarring and inflammation that can impair fertility in both women and men. Early testing helps reduce this risk significantly.
Can you have chlamydia for years and not know?
Yes. Chlamydia is frequently asymptomatic, meaning many people carry the infection for months or even years without experiencing any noticeable symptoms. Regular screening is the most reliable way to detect it.
How long can you have chlamydia without knowing?
There is no fixed time limit. Some individuals carry chlamydia for weeks, months, or even years without awareness. The infection does not resolve on its own, so it can persist indefinitely until identified through testing.
Can chlamydia go away on its own?
No. Chlamydia does not go away on its own. Without appropriate healthcare services, the infection will remain in the body and may cause progressive damage to the reproductive system over time.
Is chlamydia curable?
Yes, chlamydia is curable. Once identified through testing, you can seek medical advice to address the infection through appropriate healthcare services. However, any structural damage caused before the infection is identified may be permanent, which is why early testing is so important.
How quickly does chlamydia show up?
Symptoms, if they appear at all, typically develop within one to three weeks after exposure. However, many people remain asymptomatic, so waiting for symptoms is not a reliable strategy — testing provides a clear answer.
Can you get chlamydia using a condom?
While condoms significantly reduce the risk of chlamydia transmission, they do not provide absolute protection. Incorrect use, slippage, or contact with uncovered areas can still allow the bacteria to spread.
Can you contract chlamydia without intercourse?
Yes. Chlamydia can be transmitted through oral and anal sexual contact, genital-to-genital contact without penetration, and from mother to baby during childbirth. It is not limited to vaginal intercourse alone.
What are the long term risks of chlamydia?
Long-term risks include pelvic inflammatory disease, fallopian tube scarring, ectopic pregnancy, chronic pelvic pain, epididymitis in men, and reduced fertility. These complications are largely preventable through early detection and testing.
How to tell if you have chlamydia?
Because chlamydia is often asymptomatic, the only reliable way to know your status is through laboratory testing. Symptoms such as unusual discharge, discomfort during urination, or pelvic pain may suggest infection, but their absence does not rule it out.
Does oral chlamydia cause infertility?
Oral chlamydia itself is unlikely to directly cause infertility, as it affects the throat rather than the reproductive organs. However, it can act as a reservoir for reinfection of genital sites, which may indirectly contribute to reproductive complications if left unaddressed.
What are the long term consequences of untreated chlamydia?
Untreated chlamydia can lead to pelvic inflammatory disease in women, epididymitis in men, chronic pelvic pain, ectopic pregnancy, and reduced fertility. The infection may also increase vulnerability to other sexually transmitted infections. Early testing is the most effective way to prevent these outcomes.
